=“”

遵循以下原则：https://www.youtube.com/watch?v=iu3a0kf6-Fw 我刚开始并尝试连续上传3张图片，每张图片都是手势检测器的一个子对象，我首先在pubspec.yaml中编写了此图片：

assets:

  -wedn2\1.jpg
  -C:\Users\pc\Desktop\wedn2\wedn2\2.jpg
  -C:\Users\pc\Desktop\wedn2\wedn2\3.jpg

然后在主飞镖中，将图像放在列表中：

List<String> fileNames = <String>[
  'assets/photos/wallpaper-1.jpg',
  'assets/photos/wallpaper-2.jpg',
  'assets/photos/wallpaper-3.jpg',
];

然后我自己在行中这样写：

Row(
                      mainAxisAlignment: MainAxisAlignment.spaceBetween,

         children: fileNames
                  .map((name) => GestureDetector(

                      child: Image.asset(
                        name,
                        width: 125.0,
                      )))
                  .toList(),
      ),

我明白了，我不知道这意味着什么，而移动设备上正在运行的应用程序是我之前编写的以前的应用程序！

W/Firestore(12059): (0.6.6-dev) [Firestore]: The behavior for java.util.Date objects stored in Firestore is going to change AND YOUR APP MAY BREAK.
W/Firestore(12059): To hide this warning and ensure your app does not break, you need to add the following code to your app before calling
any other Cloud Firestore methods:
W/Firestore(12059):
W/Firestore(12059): FirebaseFirestore firestore = FirebaseFirestore.getInstance();
W/Firestore(12059): FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()
W/Firestore(12059):     .setTimestampsInSnapshotsEnabled(true)
W/Firestore(12059):     .build();
W/Firestore(12059): firestore.setFirestoreSettings(settings);
W/Firestore(12059):
W/Firestore(12059): With this change, timestamps stored in Cloud Firestore will be read back as com.google.firebase.Timestamp objects instead of as system java.util.Date objects. So you will also need to update code expecting a java.util.Date to instead expect a Timestamp. For
example:
W/Firestore(12059):
W/Firestore(12059): // Old:
W/Firestore(12059): java.util.Date date = snapshot.getDate("created_at");
W/Firestore(12059): // New:
W/Firestore(12059): Timestamp timestamp = snapshot.getTimestamp("created_at");
W/Firestore(12059): java.util.Date date = timestamp.toDate();
W/Firestore(12059):
W/Firestore(12059): Please audit all existing usages of java.util.Date when you enable the new behavior. In a future release, the behavior
will be changed to the new behavior, so if you do not follow these steps, YOUR APP MAY BREAK.

有什么主意吗？预先感谢。
